can use the differential pressure chart to estimate the approximate
clean pressure drop across a temporary cone or basket style strainer.
The chart data is based upon water and perforations ranging from
1/8" to 1/16".
To approximate the pressure drop for mesh lined
temporary cone and basket strainers apply the following multipliers to
the chart data.
- 40 mesh: 1.2 multiplier
- 60 mesh: 1.4 multiplier
- 80 mesh: 1.6 multiplier
- 100 mesh: 1.7 multiplier
As an example, the estimated clean differential pressure for a flow
rate of 60 GPM with a 2" size temporary cone or basket strainer is 2
PSI; if it were a 60 mesh lined configuration, it would be 2 PSI x 1.4 =
